More S55 tuning results with the EcuTek software suite are being published and Snail Performance did a custom Stage 1 tune on this F80 M3 Competition. This tune was done on a stock car on 91 octane pump fuel with no other changes but the tune.
The baseline is a healthy 415 rwhp and 427 rwtq on a Mustang dynamometer:
They get gains through the curve starting with a nice torque increase at 3000 rpm. There is a difference of roughly 90 whp at 5500 rpm.
Peak horsepower increases by 32 at the wheels and torque increases by 61 lb-ft at the wheels.
Very nice gains tune only over an S55 Competition file and it is great to see more and more EcuTek results especially from their ProEcu tuners.

DTM (Deutsche Tourenwagen Masters or German Touring Car Masters) is going to turbocharged four-cylinder power. The series previously utilized naturally aspirated 4.0 liter V8's but Audi states they are getting more power out of the four-cylinder turbo motors and also making racing potentially more exciting.
There is a push-to-pass feature which allows overboost for overtaking. This is a smart way to take advantage of the turbo powerplant in racing and one has to wonder why Formula 1 does not incorporate something similar to increase passing and make races more exciting.
Maybe you get a bonus use of the overboost feature if you set a fastest lap for example? There are plenty of ways to utilize the ability of the motor to generate more boost in a race setting.
Speaking of boost, the motors are designed for 50 psi.
The smaller four-cylinder motors are expected to provide a fuel efficiency benefit as well and consume 24.7 gallons an hour. This goes up to 26 gallons an hour with use of the horsepower boost function.
The motor is lighter as well with the powerplant coming in at 187 pounds. That means cars are down to 2200 pounds dry.
DTM is essentially German Nascar but with these new changes as well as lighter and more powerful cars the racing should be much more exciting.

The next generation BMW 1-Series and 2-Series will share a Mini inspired FWD architecture. What does this mean? It means four-cylinder power and it also means do not expect another M2 with BMW M inline-6 power.
Much like the BMW F48 X1 and F39 X2 which share the same platform as well there is no room for an I6 in the engine bay.
This means the redundancy between the M2 and M4 will come to an end and that the 1-Series and 2-Series are expected to stay smaller compared to the 3-Series and 4-Series which continue to grow in size.
If we even see another M2 expect four-cylinder power although that is unlikely. It would be nice to see BMW challenge the Mercedes CLA45 AMG as the 2-Series Gran Coupe in particular will be the direct challenger from BMW.
We'll see the new 2-Series debut late this year at the Los Angeles International Auto Show.

You all likely remember the name @Sendit_e90 as his E90 335i set the N54 stock turbo 1/4 mile record earlier this year. Since then he updated his 335i with a new build including a single turbo conversion and a built 6HP21 automatic transmission.
The result is a new N54 platform 60-130 record of 5.16 seconds:
Does the car have weight stripped out? Yes, as last report it weighed 26XX pounds.
A record is a record and those who want to debate between full weight street cars and stripped out drag cars certainly can as many members did for page after page after @Sendit_e90 set the 1/4 mile record on factory turbos.
Regardless, this is a quick sprint and maybe we'll see an N54 dip into the 4's 60-130 which would be a considerable stride for the platform.
Mod list:
- Stock N54 motor
- Built auto trans
- Stock diff
- 110 race gas
- Stage 2 LPFP
- 7675 Comp Turbo
- 25 psi of boost

Guys yes the BD was faster during their run, but they have ran pretty matched up times so far. One is a setup that has been repeated about 200+ times (68mm vtg) just by the one tuner alone, the other one is exactly that... One! I am sure there will be some improvement.
I am happy to see at least two shops pushing the 911 platform to amazing levels!
I am not sure about the GT2RS turbos as of yet, mostly because of price since they cost i believe in the 15K range, but if the price drops, or maybe we can locate them directly from BW, it adds a lot of additional cost to the typical build for similar performance.
I would love to see them perform on longer runs like 1/2 mile. It can be possible that they might outperform the 68s just because of size. Maybe same power with less boost, lower EGTs, etc...
Fadi's car did run in the 9.5s first time around which is amazing and he also posted 60-130 runs in the high 4s! that's super fast!
I will waiting for a few more months to maybe see more data or more cars on the GT2RS turbos to make my decision of moving from a St.2 to a St.4. I would also love to see data how these compare to a typical non-vtg gt30 setup, especially drivability and torque down low...
